Answer:
The force is Inertia
Explanation:
This is an example: He turns the ketchup bottle at an angle toward his plate and smacks the bottom of the bottle until the ketchup comes out. How does inertia affect the ketchup in the bottle? The Inertia keeps the ketchup in the bottle. The Jacksons are driving to the lake when a car in front of theirs slams on its brakes.
Your welcome! :)
Substitution is The answer
Oh okay the first person who answered is incorrect but
0—> PE=0J
1—>PE=1J
20—>PE=20J
50—>PE=50J
100—>PE=100J
Answer:
v = 2.5 mi/h
Explanation:
The velocity of an object is defined as the time rate of change of its position. In other words the velocity of an object is just a ration of displacement covered by the object to the time taken by the object, to cover that distance. So, in this case we will use the same formula or equation to calculate the velocity of the man. The formula is as follows:
v = s/t
where,
v = velocity of the man = ?
s = distance of the trail = 5 miles
t = time required to complete the trail = 2 h
Therefore,
v = 5 miles/ 2 h
<u>v = 2.5 mi/h</u>
Answer:
a)27.3N
b)150.78N
Explanation:
Having in mind the conservation of energy, as the monkey goes up (gaining potential gravitational energy) the kinetic energy must be reduced, so reducing the velocity of the monkey. So the maximum velocity will be at this lower point with a velocity of 1.36m/s
From this velocity and the radius we can calculate the angular velocity for the monkey center of mass:
with this we can calculate the centripetal force magnitude:
On the mokey center of mass we have two opposite forces acting, the tension of the arm and the weight, in order for the monkey to continue swinging the resolt of this two forces must be equal to the centripetal force:
